Apple's proposals for transforms, transitions and animations have been
updated today. You can find them at:
http://webkit.org/specs/CSSVisualEffects/
The most significant changes are splitting 2d and 3d transforms into
separate documents and adding a list of properties that can be
animated (and how to interpolate different property types).
Here is the Changelog.
CSSAnimation.html:
* animation-name should accept IDENT not <string>
* animation-play-state marked as "about to be removed"
* more description of when an animation is applied, that
they snapshot keyframes and values as they start and
how they need to be removed to reset.
CSSTransitions.html:
* list of animatable properties and how to animate property
types.
* specify that values for bezier points outside of [0,1] are
invalid.
CSSTransforms.html:
* split into 2d and 3d specifications
* transform-origin now matches background-position definition.
* describe how to animate between lists of transforms
CSSTransforms3D.html
* new specification which is the 3d parts of transforms
* perspective must be > 0
* perspective-origin also matches background-position
* describe how to animate between lists of transforms, but this
time in 3d which is harder.
Reviews, comments, etc most welcome.
